Yeah, also it's good to remember how long an addiction has been around.
You can't really change years of a specific behavior overnight.
It takes a long time to actually rewire the brain, but it is absolutely worth it.
You end up being a different person, because you literally change your brain over time.
No matter how hard it is to change someone's behavior, I think it still has a chance to change, especially if there is a strong effort from that person to try to change their behavior. If they really want change and are willing to do what needs to be done, they can do it, especially if people close to them are willing to help them through it all. This will not be difficult for the person and his family because they will help each other to survive even in difficult conditions. But the problem is that maintaining the desire to persist will inevitably lead to temptations that can make them return to gambling again.
All changes must always begin with strong intentions and sincerity from themselves and that means it's useless if many people help even some professionals who are considered to be able to overcome it but still in the end it will be very difficult to do, actually all addicted gamblers can recover by themselves if they have admitted their mistakes and have the intention to change, although the process is not easy and not fast but it doesn't matter because there will always be a process for success.
The awareness and desire that comes out of oneself for a change and also in combination with the help of the closest people I think it will enlarge or even facilitate the recovery process, as we know that the disease of addiction lies in the human brain and if they are already aware of it then obviously they only have to follow some directions suggested by the people closest to them, But before that it is also necessary to consider whether the advice is really good and leads to a change or not, yes I understand it is quite difficult to maintain the struggle for change consistently because the temptation of gambling will always cross his mind, but I think the people closest to him should be able to limit his activities, such as limiting the use of gadgets to avoid.
